Water to ice in 90 seconds using vacuum

This video will demonstrate how to make ice by boiling water using an Edwards vacuum pump in 90 seconds. Liquid boils when the vapour pressure of the liquid is equal to the pressure exerted on it. When pressure on a liquid is reduced the vapour pressure is also reduced and the boiling point drops. See our demonstration or visit _www.edwardsvacuum.com to find out how vacuum works.
